2FA (Two-Factor Authentication)

What does 2FA (Two-Factor Authentication) mean in crypto terms?

Two-Factor Authentication (2FA) is a security mechanism that requires a user to provide two types of identification to access an online account or service. Typically, one of the factors is something the user knows (such as a password), and the second factor is something the user has (such as a smartphone). A common form of 2FA is a code sent to the user's phone or generated by an app, which must be entered along with the password. 2FA adds an additional layer of security, making it harder for unauthorized users to gain access to accounts, even if they have the password. It is widely recommended for securing online accounts, especially those related to finance and sensitive information.
